Joshua recently spoke to the press about his character Peter in the final season of Fringe.

“Peter essentially committed the exact same sin his father did, which is a totally understandable … I mean, part of what was always so dynamic about the thing that Walter did wrong is, I think, just about any person — not even any parent — can understand why. He had lost his child and was given an opportunity to have his child back. You would have to be Jesus to say, ‘No, actually. That’s wrong.’ So everybody gets that,” Joshua shared. “And Peter, I think, in much the same fashion, wasn’t capable of processing that. And you know, I think he pushed everyone in his life away. He pushed Olivia away, I think, because he just couldn’t accept the idea that he wasn’t going to be able to fix this.”
